VVBe it known that l, lTJiLLmir J. Hoornn, a ctizen of vthe United States, and a resident the city of lerlreley, in the county of Alameda and State of California, have invented a new and useful Separator, of which the following is a speciiication.

rllhis invention relates to a device for separating particles suspended in a gas or carri-ed by a gaseous stream. Such a device may be arranged in the path of movement of. .the gaseous stre in, and the gas in moving through the device is caused to separate from the particles carried thereby, whether these particles be verv fine, as found in steam or smoke, or of comparatively large size, as glowing cinders in a smolre sta-ch or flue.

lt has been proposed in the past to provide such separators in which helicoical pas-A sageways are provided for the gaseous stream. 'lhe suspended particles carried into the passageways by the stream are urged by centrifugal force due to the rotary motion in the passageways, away from the axis of the stream and through appropriate openleading to another receptacle where the particles are collected and removed.

lt is one of the objects of my invention to improve in general separators of this Vcharacter, and to male it possible for such separators to extract more perfectly the particles carried by the stream.

ln this connection it is a. further object of my invention to provid-e substantially continuous spiral-like passageways between an outer collecting chamber and the inner chamber through which the gaseous stream passes. Due to this construction the i) plane 33 of Fig. 2; and

Fig. is a section of the spiral strip wht f forms the helicoidal passageway in Y the nier chamber. f

ihe separator' has an intalre nozzle or 'passageway ll near the bottom thereof as shown in Fig. l. At the top the outgoing chamber, formed by wall 7 may connect inV separated particles are guided substantially continuously to the external collecting chamber through expanding passages.

lily invention possesses other advantageous features. some of which with the foregoing, will be set forth at length in the following description, where l shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification.

Although l have shown in the drawings but one form of my invention, l do not desire to be limited thereto, since the invention as defined in the claims, may be embodied in other forms also.

Referring to the drawings:

passageway l is shown, whence the puriiied stream may be conducted to any desired .locality or to the atmosphere. has an inner chamber formed by a series of ovcrlappino` vanes 6 (Fig. 2), forming tangential slots connecting this inner chamber with an external annular chamber l2, formed by the aid of an external wall 7. These venes serve as doflectors and are preferably substantially spiral in cross section. rlhe rEhe separator turn to a collecting space, which may be provided either by a separate vessel or integrally, as is shown in the present instance. Thus the wall 7 is shown as formed integrally with a base 13, having a sloping interior surfacey le leading to a discharging outlet 15. The outer chamber 7 is closed at the top by the cover 17, which also serves to hold the vanes 6 in a rigid manner, and to provide the discharge outlet 1l. This cover may be fastened in any appropriate manner to the outer wall 7, as by the aid of the overhanging walls of the cover.

ln order that the suspended particles can ried by the gaseous stream be urged through the slots formed between the vanes 6, it is necessary to cause the gaseous stream to rotate, at the same time that it advances through the inner chamber formed bythe vanes 6. rlhis 'is eil'ected by the aid ot' a spiralling strip 5 shown in greater detail in Figs. 3 and el. llhis strip 5 is twisted to form a pair of helicoidal passageways for the gases through this inner space. The

pitchV4 of the helicoid is quite steep, and .its

length is substantially identical with the length of the vanes 6, as shown most clearly in Fig. 3. As the gases pass through nozzle ll they divide into two streams which are separated by the strip 5. The gases are thus given a spiral rotary motion through the inner chamber. The particles carried by the lll lill) streznn ure caused due tu die motion of The treuni re nieve euwurdly towards the Slots between he ovezirgping venes (i und 51121112; to einer iure the Outer chamber l2.
